One arrived with no cap. You'll have to re-glue the caps on everyone of these. The set screw will strip out from a small amount of torque. These are absolute junk.

Two of the knobs (out of 10) did not fit onto 1/4” pot shaft. Required internal de-burring. Minor problem that explains the need to “b-stock” clearance these items. No regrets here. I got around the problems.

My 1987 2554 Silver Jubilee's original push-pull knobs (set screw type) were cracked & unusable.
The replacement P-K392X set-screw knobs look & feel identical to the originals Marshalls.
In fact, they are an improvement; having brass inserts for the set screws; not just plastic (like the Marshalls).
They will not have the same cracking issue.
This Amp has been my #1 since purchasing it in 1987 with my first paycheck.
Thanks Amplified Parts!

Great quality knobs, easy fit and the brass grub screws are a nice detail.

These are excellent Marshall style knobs. They are of great quality and are just as good or better than the original ones on my 1990 Marshall 1962 reissue amp. I got these to replace the original push on knobs on the amp. I recently replaced all of the old worn out potentiometers in my amp from old knurled shaft pots to new solid shaft pots and needed authentic looking and quality Marshall style set screw knobs as replacements. By the way the set screw is brass and of good quality. These knobs look and feel just like the original ones and in my opinion are of a slightly better build quality. These in my opinion are more solid than the original ones on my amp. Cosmetically they look the same. If you have a Marshall amp that came originally with silver cap knobs, these are the ones to get, as Marshall no longer seems to make and sell these knobs with silver caps. At least I have not seen them from Marshall in a while. They only sell them in gold. My original ones were silver cap knobs just like these replacements and my amp looks really good with them and retains its original look. One last thing, the price of these knobs is excellent considering their high quality. I highly recommend them.
